Re headset: I found a NOS Stronglite A9, ISO. If I am reading the specs correctly every single dimension on the headtube/fork is the same from Italian to ISO except the threads are cut 55deg (as opposed to standard 60deg I presume) and the ID of the crown race is off by .1mm. This leaves 3 options:
1. reducing the diameter of the fork
2. enlarging the ID of the Stronglite's race
3. re-using the existing race.
I do have a lathe and could likely attempt #2. I would need to test fit to determine if #3 works with the stronglite's bearings. Curious to hear from anyone who has attempted same.
Does anyone know if friction shifter bosses are universal or Country / Manufacturer specific? ie: can I replace the Campy friction shifters with (other) such as Dia Compe while reusing the clamp-on boss?
